Repoint the sendmail relay-host to <new-host>

[terrytapp]

My task is to repoint the sendmail relay host to the new server name. I have to do this on 11 servers. What exactly should i do (or change in the sendmail.cf file) also should i stop and restart the daemon? Please advice.

Thanks

Terry

change the conf file and than restart.
the relay is configured ad:
grep ^DS /etc/mail/sendmail.cf

[Anshumali]

you should edit sendmail.cf and enter the value here..
# "Smart" relay host (may be null)
DS

you can send a HUP signal as well to ask sendmail to reread its config file...

I have changed the relay host from

DSoldserver.com to DSnewserver.com and restarted the sendmail. How do i verify this change? Please help.

Thanks

Hi Terry:

> I have changed the relay host...How do i verify this change?

Send a mail:

# mailx -s "Test_Message" somebody@xyz.net < /dev/null

...where "somebody@xyz.net" should be addressable by your configuration.

You can examine '/var/adm/syslog/mail.log'.

Regards!

Thanks!!

this is what i did..

sendmail -v and i get the message

# sendmail -v terry@abs.com
this is a test
terry@abs.com... Connecting to abs.com (tcp)...
terry@abs.com... Host unknown
Saving message in //dead.letter
//dead.letter... Can't create output

Thanks
